.SH DESCRIPTION
As part of the Performance Co-Pilot Log Import API (see
.BR LOGIMPORT (3)),
.B pmiPutValueHandle
adds a single value to the current output record for a given
metric and instance, using the
.I handle
defined by an earlier call to
.BR pmiGetHandle (3).
.PP
The
.I value
should be in a format consistent with the metric's type as
defined in the call to
.BR pmiAddMetric (3).
.PP
No data will be written until
.BR pmiWrite (3)
is called, so multiple calls to
.B pmiPutValueHandle
or
.BR pmiPutValue (3)
are typically used to accumulate data values for several
metric-instance pairs before calling
.BR pmiWrite (3).
.SH DIAGNOSTICS
.B pmiPutValueHandle
returns zero on success else a negative value that can be turned into an
error message by calling
.BR pmiErrStr (3).
.SH SEE ALSO

.BR pmiErrStr (3),

.BR pmiPutResult (3),
.BR pmiPutValue (3),
.BR pmiPutText (3),
.BR pmiPutLabel (3)
and
.BR pmiWrite (3).
